ARGONNE NATIONAL LABORATORY/ISIS NEUTRON FACILITY POSTDOCTORAL POSITION The Materials Science Division at Argonne National Laboratory is seeking candidates for a postdoctoral research associate position in neutron diffraction. The successful candidate will be located predominantly at the ISIS pulsed neutron facility at the Rutherford Appleton Laboratory in the UK. The research involves using the new high-intensity powder diffractometer GEM and other state-of-the-art facilities at ISIS to study the structural and magnetic phase diagrams of materials displaying subtle transitions driven by parameters such as composition, temperature, magnetic field and pressure. With the advent of GEM, it has become possible for the first time to obtain high-precision structural parameters, often comparable to those from single crystals, with a few minutes' data acquisitions. Therefore, multi-dimensional phase diagrams can be constructed using internal structural parameters, such as anisotropic Debye-Waller factors. Because of the absolute accuracy of these parameters, close comparisons with lattice dynamics models are also possible. Areas of science that will be the focus of this work include existing and new research programs at both ISIS and Argonne, namely: magnetoresistive materials, including both perovskite and layered compounds, magnetoelastic materials, ferroelectric materials, ionic conductors including battery and fuel-cell materials and ceramic membranes. Candidates must have a Ph.D. in Physics, Chemistry, Materials Science or related subject. Experience in neutron scattering or diffraction and computer analysis/programming is preferred. Postdoctoral appointees at Argonne much have received their Ph.D. within the last three years. The deadline for applications is July 10, 2001 or until the position is filled. Please send applications, including a resume and publication list to Dr. James D. Jorgensen, Materials Science Division, Argonne National Laboratory, Argonne, IL 60439 ([EMAIL PROTECTED]). Further information can also be obtained from Dr. Jorgensen or Dr. Paolo Radaelli ([EMAIL PROTECTED]).

Women and minorities are especially encouraged to apply.
